QL40-NEU – Neutron Thermal Neutron

Description

The QL40-NEU neutron probe utilizes a He-3 thermal neutron detector. It measures Neutron porosity in counts per second, which can be directly related to the porosity of the formation. The probe has been carefully designed to maximize the detector sensitivity so that good results can be achieved with source strength of only 1 Curie. The source is carried in a specially designed shield and the probe itself is the source handling tool.

The QL40-NEU tool is stackable within the Quick Link (QL) product line or it can be run as a standalone tool. It can be run in any borehole environment.
